Point Light Walkers (PLW) is a user-friendly toolbox for MATLAB (or GNU/Octave) that aims to aid biological motion research in psychophysics providing:

• support for read/write access to scientific data format HDF5;
• various straightforward psychopysics experimental design;
• 4 dimensional data transformation repreasenting biological motion animation in 3D space;
• high precision on-the-fly visualization built upon Psychtoolbox (using OpenGL);
• visual, auditory and tactile simulation with high precision response capturing;
• semi-automated data cleansing and data analysis (ANOVA, MAVONA, rANOVA and more);

1. Download the .zip file from this Github page;
2. Install Psychtoolbox 3.0 if you are using PLW with Psychtoolbox;
3. refer to ./lib/RL_PLW which serves as the API to this library ;
4. use scripts under ./lib/data/ for data analysis;
